The flywheel are easier to remove from these engines compaired to the a1.Ive never been able to remove an a1 flywheel without damaging the thing, but the a type engine seem to come of no probs with a bit of patiance.

i found the noise, it was the fixed shaft that the starting gog/gear sits on this has now been repaired ( i knew the lathe would get to do a serious job eventualy). all i need now is a better set of timing gears the set on the engine are very worn and chattery. i've put an add in SE so we will have to wait and see.Earl.
